To all whom it may concern:

Be it known that I, EUGENE N. HUNTING,

of Youngstown, Mahoning county, Ohio,

have invented a new and useful Improvement in Reinforced Concrete Structures, of

ing one form of my improved beam and girder connection; Fig. 2 is a sectional elevation of the same; Fig. 3 is .aplan view' showing a modification; and Fig. 4 is a sectional elevation of'the construction shown in Fig. 3.

My invention relates to reinforced concretebeam and girder constructions; and particularly to the manner of disposing of and connecting the ends of the reinforces in such structures, the object being to provide for the connections of the ends of the reinforces in such a manner that the stresses will be transmitted by the metal directly through the vertical columns or posts of the structure without dependin upon the concrete in which the metal 1s embedded to transm it such stresses.

and 4; the connecting horizontal beams. Em-

bedded in each of the concrete beams 8 and 4 is a metallic reinforcing truss which, in the present instance, is composed of an'upper member or chord, a lower member or chord, and a series of oblique bracing members. The upper member 5 of the reinforce in one of the beams 3 has its end portionbent at right angles into one of the transverse beams l. as shown at 5", while the upper chord 6 i. the other beam '3 is similarly bent at right angles in the opposite direction into the :other beam 1, as shown at 6. In a like mannor, the upper chords 7 and 8 of the reinforces in the beams 4 are bentat right angles in. opposite directions and these bent portions are extended into the respective beams as shown at 7 and 8. 9 designates the o lique bracing memberswhich may or may not be employed,

The bent end portion of each of the upper chord members "is secured by one ormore sleeves or clamps 10to theadjacent reinforcing member .and the beam-into WlllCll is bent and alongside of which 'it lies. .Into each of the sleeves or clamps is driven a. wedge l'l which closely binds the mem -bers together, The-lower chords 12 of each of the reinforces may simply extend'into the column and terminate therein, or they may,

as shown, be connected in precisely the same manner as the upper chords. That is, each lower member is bent at right angles into one of the adjacent beams and is secured to the mainreinforci'ng member in that beam; This construction provides for a very secure and rigid connection for the ends of the reinforcing members, each member having a portion bent to form a part of the'reinforcc of another beam. In-this manner, a strong central connection is effected and the stresses on the reinforces are communicated through the metallic members directly from one to the other, withoutdependence upon the surrounding bed of concrete.

In the construction shown in Figs. 3 and 4, the ends 13 of the upper and lower chord members, instead of being bent horizontally into an adjacent beam are bent vertically at right angles, the ends of the upper chord members being bent vertically upward into the vertical post or column 2*, while the ends of the lower chord members are bent vertically downward into said column. Those bent ends are brought into close relation to each other and'are securely bound together by clamps 14, which may be similar to the clamps 10. In this construction, the ends of the reinforces are also directly connected to each other so that stresses are directly tion" of the reinforce itself. These rein-- forces may be metal bars of any desired central column, and'a plurality of -concrete beams joining the same, a metallic reinforcing member embedded in each beam and extending into the column, the end ortions of all the reinforcing elements being rought together within the central portion of the column and each such. portion then bent outwardly into another bean'rand secured to the metallic reinforcing membertherein; substantially as described.

2. In a reinforced concrete structure, a concrete column, a pluralit of concrete beams joining the same, a p urality of reinforcing elements extending at an angle to'each other into difi'erent beams, and having their adjacent end portions brou ht together and then bent at an angle 68,5] into another beam and secured to the metallic reinforcing member therein; substantially as described.

3. In a reinforced concrete structure, four trusses at an angle to each other, and having each an upper chord and a lower chord, the chords of each truss being bent at an angle and secured to a similar chord, in a truss at an angle thereto; substantially as described.

4, In a reinforced concrete structure, four trusses. at an angle to each other, and havin each an upper chord and a lower chor bracing members connecting the upper and lower chords of each truss, the chords of each truss bein bent at an angle and secured to a similar chord in a truss at an angle thereto; substantially as described.

5. In a reinforced concrete structure, a concrete column, radiating reinforcin trusses joinin the column, and having eac 1 an upper and a lower chord, the chords of each truss being bent at an "angle within the column and secured to a similar chord there- 111 of a truss at anangle thereto; substantially as described.

In testimony whereof, I have hereunto set my hand.
